Epigenetic alterations
Hallmark of aging62 papers9 findings
A human study links epigenetic alterations in blood to frailty, while mouse and cell experiments reveal specific genetic regulators. Reviews describe these alterations as contributing to cancer, neuroinflammation and mitochondrial dysfunction, but mitigated by exercise.
